How to freeze dry chili
A typical batch of chili runs about 36 hours in a home freeze dryer, plus about 6 hours of extra dry time. Plan on about 6 months of good quality for freeze-dried chili, as long as the food is fully dry, sealed in an airtight container or mylar bag with an oxygen absorber and stored cool and dark. These are typical estimates from the FreezeLog guide, not exact times or a safety limit. Read the safety note below before you start.
General guidance only. Follow your freeze dryer manufacturer's instructions and current food-safety guidance. These are rough figures, not a promise that any food is safe to store or eat. Actual results depend on your machine, load, packing and storage.

Safety note
Prepared meals can carry bacteria if they were handled or cooled poorly before drying. Cool and load them promptly, store them fully dry, and follow current food-safety guidance when rehydrating and eating.
How do you prep chili for freeze drying?
Cook as usual. Cool it from hot to 70 °F within 2 hours (spread it thin in shallow pans), then refrigerate or pre-freeze until it goes in. Spoon into trays or freeze into slabs.
How do you load chili on the trays?
Spread about 1 cm thick. Thicker portions need more time. Run chili in its own batch, because spiced foods pass their odor to other trays.
How long does it take to freeze dry chili?
A typical batch of chili runs about 36 hours in a home freeze dryer, plus about 6 hours of extra dry time. Your machine and load will differ, so check that the batch is dry before you pack it. Here is how to tell when a batch is done.
How do you store freeze-dried chili?
Before packing, break open the largest piece. If any piece is cold, soft or moist inside, put the whole batch back for more drying. Seal in a mylar bag with an oxygen absorber. Label with the date and store in a cool, dark spot.
What is the shelf life of freeze-dried chili?
Plan on about 6 months of good quality for freeze-dried chili, as long as the food is fully dry, sealed in an airtight container or mylar bag with an oxygen absorber and stored cool and dark. That is an estimate of quality, not a safety limit.
How do you eat or rehydrate freeze-dried chili?
Add boiling water and stir well. Allow time for beans to soften. Heat to 165 °F before eating.
